Code Signing is a process to confirm the authenticity and originality of digital information, especially software code, and assuring that this digital information is valid and additionally establishes the legitimacy of the author. It also provides assurance that this piece of digital information has not changed or been revoked after it has been signed by the signature.
Whenever we download a program or software, and we see a pop-up saying “Are you sure you want to run this?”, or when you install software and try to run it then you get asked “Do you want to allow the following program to make changes to this computer”, this is code signing in action. And if the program downloaded or installed has not been code signed, then you will see a small warning sign stating that it has not been code signed.
Code Signing plays an important role as it can enable identification of a legitimate software vs malware or rogue code. In technical terms, code signing creates a hash of the code and encrypts it with a private key adding its signature.
During execution, this signature is validated and if the hashes match, it gives assurance that the code has not been modified. It also establishes assurance that the code is issued from a legitimate author that it is claiming to be once it has been digitally signed.
